To all whom i! may concern:

Be it known that We, LEE ROBERT J. YOUNG, citizens States, residing atAkon,- in the county of Madison and State of Illinois, have inventedcertain new and useful lmprovenents in Computing feliorving is aspecification.

Qur invention relates to computing Weighing scales.

The main object of the invention is to provide e novel and e'llcientpendulum inechanism for actuating the dial vor indieatoro1 the scale.This object We accomplish by the construction shown in the accompanyingdranzvings, in which- Figure t is a Irear perspective of a coinputingscale embodying 'our improvements. Mig. 2 is a longitudinal verticalsection thereof. Fig. 3 is a side elevation of the pendulum mechanismremoved. Fig. 4 is u fragmentary elevation at the front sight opening.Fig. 5 is a detail showing the diaipinion and shaft. Fig. G is va detailsectional View of the dash pot.

The lower endv of the screw b2 has econical recess therein for a purpose to be hereinafter described.

Thediashett H is provided with en adinstable pinion it, secured toit himeans ci@ a ienge s/integral with the 'she t end haih iti@ having; an'annularly arranged serres of gradueticns uidieeting peunds and so thatthe purchaser may' V butter ing segmental slots h2 through which screwsL pass into the pinion and by means of which the pinion ma be adjusted.

A10 is a lower braeliet in the lower part otl the dial casing, to oneside of its center, and provided with bearings at al".

K is the pendulum shaft having knifeedge bearings mounted in thebearings al and K is a three-armed lever carrying the pendulum shaft atthe juncture of its three arms.

The pendulum or weight K2 is secured to the lower end of the dependingarm 7c?, and the upper end of the upper arm lf3, is bent into U-Shapeand has pivoted therein the outer end of a rack-bar L, by means of thepointed pivot screws Z, Z entering apertures in a yoke-like bracket Z onthe end of the rack. The rack-bar L is inclined on its upper edge fromits free end toward its pivoted end, and its lower toothed edge en`gages the upper side of the pinion z, of the dial shaft.

M indicates a cam-shaped actuating arm loosely mounted at its inner endon the pendulum shaft K and provided with a curved slot m, through wipasses into the middle arm 7c, of the lever K. To the upper rear end ofthe cam M, is secured the upper end of a flexible band or ribbon N,which passes around the cam surface to a point therebelow where it ispro: vided with an apertured clip n to which is connected, by a pin n',the slotted, apertured upper end of the connecting rod O, the lower cndof said rod being provided with a box loop o havin a pointed screw 0extending up through i s lower member and entering the bearing b3 in thelower end of the screw 62 at the end of the scale beam B. The 'iiexibleband or ribbon N is clamped to the cam M, by a plate m2, and screw m8,and the plate m2 and ribbon N, are held from turning on the Screw bymeans of a pin n3 xed to the cam and extending through apertures in theribbon and plate mi.

The rack bar L is held down to the inion la., of the dial v'shaft bymeans of a s iding rod P, mounted in the bracket A, near the free endoi' the rack-bar, and under which the rack-bar slides and turns aboutthe pinion. The distance fromthe dial shaft to the end of its arm its,being reater than thee distance from the shaft to t e widest part 'ofthe cam M, the are usually necessary for the knife-edge bearings of thedial sha t is considerably reduced and the danger of inaccuracy inautomatic computing scales, due to the slip ing o' the knife-edges whenbearing is great y out of the vertical, is obviated.,l

rlhe sudden downward movement of the scale beam B, is iiurther checkedby a buffer R, having a supporting screw r, mounted in a cross piece rand having a set nut r2; the being directly below the screw 0.

ich a screw m',

.therearound, a cam exten The dial casing at its front side is closed bya glass pane to protect the pendulum mechanism from dust, handling, ctc.

S, designates a spirit level mounted on lhe upper side of the base A, toenable the scale to be set perfectly level.

Our construction renders shipment easy since the only parts that have tobe removed are thc pendulum and its connected parts including theconnecting rod which are removed as a whole, and the purchaser mayreadily replace them by seating the knifeedge shaft in its bearings,connecting the connecting rod to the scale beam, moving out the rod P.till the rack has been properly adj usted and then moving the pininwardly over the upper inclined edge of the rack. The cam and thevpinion on the dial shaft being also adjustable a very ne and accurateadjustment of the dial actuating mechanism may be had. It will benoticed that as the rack is moved across the dial pinion, its inclinedupper edge will engage the guide pin and the'raclr will gradually movearound the pinion..

We do not restrict ourselves in the use of this dial or indicatoractuating mechanism to the particular form of scale shown.
